Top-notch tail and brake lights. Very strong light with a consumption of 1.5W instead of the conventional 5/21W. I highly recommend them.. The only negative is their high price. For me, they are worth it.

Easy installation, noticeable difference in light intensity between position and stop mode, compared to other LED bulbs.

Finally, a proper and worthwhile LED solution for brake lights! Amazing purchase!

However, be careful as there are 2 models in red color. One at 1.4W and the slightly more expensive one (€24) at 1.7W.
The red color is ideal if it's for the brake light – the white LED of the same wattage loses a lot of its brightness, since the brake light ends up filtering out 60% of the brightness when the LED itself is white.

When you haven't pressed the brake, the light is a bit dimmer than the conventional (incandescent) one.
However, when you press the brake, the light reaches a greater distance and is almost at the same lumens as the incandescent ones.
There is a huge difference when you press the brake and when you don't (which is very important), something that unfortunately many LED bulbs lack and are very dangerous, because you can't tell when the brake is pressed and when it's not.

The light is distributed completely evenly in the light housing and the color comes out completely bright red and not orange – as other LED bulbs do.
Also, even though it was installed in a 20-year-old motorcycle, the motorcycle's "reflector" did not cause any issues with this particular bulb – which has the LEDs facing inward, so there is no loss in brightness.

Another thing, in tests these particular LED bulbs do not exceed 50°C, so there is no risk of overheating and they are not dangerous for the vehicle – unlike no-name Chinese ones.

Previously, I had the Philips Ultinon Pro 3000 "red" LEDs, where it was barely noticeable if I was pressing the brake or not, and they also didn't shine as brightly – absolutely no comparison, plus the light housing would shine orange and not red.

One last thing, LEDs consume 10 times less than conventional incandescent bulbs, so if you have a problem with a weak electrical system (stabilizers, etc.), LED bulbs are an absolute lifesaver. However, I don't know if they are compatible with a car's CANBUS system and if they throw an error – I don't know about that... In my case, they work correctly though.

Overall, an honest – quality and proper purchase.

If you want, check out a comparison with many LED bulbs, these ones are top...

Attention to CITROEN C3 2016, they do not work properly (they blink). Finally, they were installed in another car without any problem, PAJERO PININ 2006. In terms of lighting, don't think they are super bright. They are pleasantly powerful and the good thing is that the bulb is not visible through the light (the LEDs illuminate the mirror, not directly outside). In some cars (depending on the light), like AUDI A3 8L (and there it caused a malfunction), they illuminate the same as regular ones.

It is not intended for road use.
OSRAM has other bulbs for road use, even if neither these (nor any other LED bulb) have certification for road use.

Flawless stop lights. Both in intensity, color, and alternations. Don't waste money on cheap Chinese bulbs.
